A method for evaluating the health status of the hydraulic system of a hydro-generator set

Abstract

The invention discloses a method for evaluating the health status of an oil pressure system of a hydroelectric generating set, comprising: S100, collecting analog data, switching data and text data of a governor system, an oil pressure system, a monitoring system and a production management system; S200. Preprocess the collected analog data and switching data; S300. Perform fixed value calculation on the preprocessed data, determine the fixed value and determine the size of the fixed value, and build a health evaluation model for the hydraulic system of the hydroelectric generator set ; S400. Import the preprocessed data into the health evaluation model of the hydraulic system of the hydraulic turbine generator set, analyze the operation data and analyze the operation development trend of the hydraulic system, perform fault detection and analyze the fault type and frequency of the hydraulic system, and perform defect analysis. Analyze and analyze the types and times of defects in the hydraulic system. The invention realizes all-round and real-time evaluation of the health status of the oil pressure system of the hydroelectric generating set.

Description

technical field [0001] The invention belongs to the technical field of the oil pressure system of a water turbine generator set, and in particular relates to an evaluation method for the health status of the oil pressure system of a water turbine generator set. Background technique [0002] At present, the oil pressure system has no alarm function in the case of abnormal oil quantity detection, abnormal air supply valve group, internal leakage of the system, etc., requiring staff to conduct inspections through tours, data analysis, field tests, etc., with heavy workload and low efficiency. It is not time-sensitive, and the situation has often deteriorated significantly by the time the abnormality is discovered. [0003] Specifically, the existing evaluation methods of the hydraulic system have the following problems: [0004] (1) The degree of manual participation is high, the efficiency is low, and the working ability of the staff has a great influence on the data collecti...

AI Technical Summary

Problems solved by technology

[0004] (1) The degree of manual participation is high, the efficiency is low, and the working ability of the staff has a great influence on the data collection and evaluation results;

[0005] (2) The data indicators are too single or scattered, which cannot accurately reflect the hidden dangers of the equipment, and the hidden danger investigation is difficult;

[0006] (3) The cycle of data collection and analysis is fixed, the timeliness of data is poor, and the operating conditions of equipment cannot be reflected in time

[0007] The equipment setting often has its own working characteristics, and the corresponding setting basis cannot be found in the relevant national and industry standards. The on-site staff often conduct debugging based on experience and tests. Not only the test cycle is long, but also there is a greater safety risk in the test process
